I have a Cannon PowerShot camera. When I take videos it records .MOV files.

On Windows 10 I use Picasa to organize my pictures. To import and view MOV files in Picasa I need to install QuickTime.

Regrettably, the QuickTime installer doesn’t work on Windows 10.

One “recommended workaround” is to install the K-Lite Codec pack. When I tried to install it I was prompted by this crap:

This is malware. Always click Decline.

This is the primary reason why the Windows software ecosystem sucks. Searching for straightforward solutions lands you on the worst snake oil and sleaze bag sites. They embed their garbage in “next next” dialogue hell.

Always pay attention when installing software because often, a Windows software installer includes optional installs, such as this MyStart toolbar which is essentially a Trojan horse.

PS: The K-Lite Codec pack did not solve my problem. I uninstalled and opted for QuickTime alternative instead.
